11 Claims.

to improveof a class known as Veneparticularly to improveand bracket supporting This invention relates generally ment in window blinds tian blinds, and more ments in the head-bar means therefor.

The present application constitutes a division of an application filed May 1, 1935, hearing Serial No. 19,184, issued as Patent No. 2,072,464, March This invention has for an object the provision of structure wherein the head-piece or casing thereof may be simply and conveniently adjusted longitudinally to properly fit window easements of different widths.

Heretofore, in Venetian blinds the mechanism for raising or tilting the slats has been exposed, and could not be conveniently removed for cleaning purposes. It is a further object of this invention to provide a Venetian blind in which all of the operating mechanism is concealed from view in a casing, and yet provide means for readily detaching the casing from supporting brackets so that the mechanism can-be easily cleaned and oiled when necessary.

Another object of the present structure is to provide an arrangement of pulleys with relation to the operating mechanism whereby the operation thereof is unafiected when the casing is longitudinally adjusted.

This invention presents a Venetian blind headpiece and bracket construction which is mechanically. durable and substantial, yet light in weight, extremely compact and inconspicuous,

, neat and good looking, readily removed from the 35 supporting brackets or replaced thereon .in a simple manner by anyone having no particular skill.

A iurther object of this invention is the provision ofstructure whereby the control or opcrating cords of the blind-operating mechanism are maintained at a predetermined distance from the vertical frame membersof thewindow casement regardless of the horizontal longitudinal adjustment of the head-piece.

Another advantage of the present invention lies in the fact that the head-piece structure and brackets therefor may be utilized with Venetian blind assemblies having various types of slat tilt- 50 ing and elevating mechanisms.

A still further advantage of the present con- 7' struction resides in the simplicity in' manufacture and assembly, together with the adaptability of the parts wherein slight changes in assembly 55 permit blinds of extreme variations in width to be constructed with consequent reduction in manufacturing costs.

These objects and further features, incidental ends and advantages will more fully appear in the progress of this disclosure the appended claims.

In the accompanying drawing, similar reference characters designate corresponding parts throughout the several views in which:

Figure .1 is a fragmentary elevational view 10 showing a Venetian blind embodying the present invention.

Figure 2 is an end view in elevation of a casing or head-piece of a Venetian blind supported on a bracket, as embodied in the present inven- 15 tion. e

Figure 3 is a plan view of the head-piece partly broken away as supported on the brackets therefor. 9 p

Figure 4 is a vertical sectional view of Figure 3 taken along the plane 4-5 thereon.

The head-bar, head-piece frame, or casing indicated generally'by numeral I0 is composed of a main body portion II which is substantially U- shape-in cross section (see Fig. 2), and a shiftable member l2 at each end thereof extendible with relation: to portion II. The extensible members l2 are shaped to correspond with the configuration of body portion ii and to'nest therein, being retained in position by means of the screws 30 iii in threaded engagement with said members. Screws l3 freely penetrate longitudinally directed slots I located in.the bottom wall of the body portion I I, while the heads of said screws engage the lower surface of said body portion II. It may thus be seen that when screws l3 are loosened the shiftable members 12 maybe moved longitudinally with relation 'to body portion ll. After members I! are placed in proper position the screws I! are tightened thereby fixing said 40 members in place. It is to be noted that this last mentioned adjustment is made only once, at a time when the Venetian blind assembly embodying this invention is installed in a given window casement. I

The front vertical wall I I of each of members I2 is preferably coextensive in height with the front wall of body portion ll thereby promoting a neat appearance of the casing III as best seen in Figure 1 of the accompanying drawing. The rear vertical wall I of each of members I2 is shown as comparatively reduced in height thereby resultingin a saving in material and weight.

It is to be considered however, as being within the scope of this invention to increase the height and as pointed out in 5 Each of the members I2 is carried by a bracket l I, by resting upon an inwardly extending flange l8 horizontally bent, from said bracket. Flange I8 is continued intoa vertically bent portion l8 which serves as a transverse limit or stop. The

' horizontal portion ofsaid flange I8 is provided with an open ended-slot l9 transversely disposed relative to the casing l0. Each of the members I2 is provided with a thumbscrew 20 which freely penetrates slot is and is in threaded engage-v ment with said member.

In the installation of this Venetian blind assembly, the brackets II are attached to the window casement 2| in any suitable manner as for example by screws (not shown) penetrating the orifices 22 in the brackets H. The position of members 12 is adjusted relative to the body portion H in a manner described above so that the thumbscrews 20 may be inserted into the slots [9. When the members l2 are in the position shown in Figure 3, .or fully seated, the thumbscrews 20 are tightened thus locking the casing ill in place. When the position of, members l2 has once been determined, as statedabove, removal or replacement of the casing lil requires only the manipulation of the thumbscrews 20. The outer vertical edge of each wall l may be extended to cover a portion of the bracket 11 as shown in Figure 3 or to disclose same as seen in Figure 1.

- Numerals 23 and 24 designate operating cords which control any suitable slat tilting and elevating mechanisms as for example those shown, and more particularly described in my co-pending applications bearing-Serial Nos. 19,184 (May 1, 1935) and 50,122 (Nov. 16, 1935).

The cords 23 and 24. pass over idler rollers or pulleys 25 which may be single or pairs of independent rollers as desired, and thence downward ly through the casing Ill. The body portion It is provided with open ,ended slots 26 in each end of the bottom wall thereof, while the members l2 are suitably oriflced as at numeral 21 so' that these openings are aligned and the cords 23 and 24 are given unobstructed passage therethrough regardess of the normal displacements of the members l2 as inhibited by screws l3 in slots H.

The pulleys .25 are mounted upon the members 12 and shift therewith, said mounting being accomplished in any suitable manner but preferably by trunnioning in irregularly shaped inverted- U-shaped brackets 28 aflixed to members l2 for example by spot welding. The configuration of brackets 28 is illustrated in Figure 2.

From the above description it will be seen that the present invention provides for a Venetian blind which can be manufactured in standard sizes and conveniently adjusted to permit installation in window easements of various widths and that no particular skill is required to do so,

while removal and replacement is also a simple matter.

The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as restrictive or limitative of the invention, of which obviously an embodiment may be constructed including modifications without departing from the general scope herein indicated and denoted in the appended claims..
